[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pouring cap, and more particularly, to an improvement of a pouring cap in which a lid is hinged so that it can be opened and closed by an inversion hinge mechanism.

[0002]

[Prior art] [Problems to be solved by the device]

 As a pouring cap, it is known that a cap is integrally formed with a cap base via an inversion hinge.

When these caps are opened or closed to a predetermined position, they are automatically opened or closed by the action of the reversing hinge mechanism, and the closed state or the opened state can be stably maintained and handled. It is convenient and can be manufactured at a low cost because it can be formed by integral molding of synthetic resin. However, when opening the lid, the inversion hinge mechanism must be opened unless the lid is opened to a relatively wide opening angle. Does not act in the opening direction, so it is relatively difficult to open the lid easily with only one hand holding the container.

The present invention has been made in view of the above points, and in this type of cap, the lid can be easily opened with only one hand holding the container, and even if the container is accidentally tilted, the lid can be opened. Therefore, it proposes an excellent spout cap that prevents liquid leakage.

[Means for Solving the Problems]

 In order to solve the above problem, the cap of the present invention is a pouring cap in which a lid 3 is hinged to a cap base 2 by a reversing hinge mechanism 4 so as to be openable and closable, and slides on the upper surface of the cap base 2. A push button 5 having a plate portion 20 is provided, a taper portion 22 is formed in the front portion of the sliding plate portion 20, and the front portion of the lid body 3 closed by the taper portion 22 can be pushed up. While the front end of the push button 5 is pushed into the recess 9 provided on the front surface of the cap base 2 so as to be protruded, the rear edge of the sliding plate portion 20 can be brought into contact with the back surface of the reversing hinge mechanism 4. When the sliding plate portion 20 is retracted by providing the front edge of the push button 5 with the provision of 25, the taper portion 22 pushes up the front portion of the lid body 3, and the protrusion 25 of the reversing hinge mechanism 4 is used. The back side is pressed to open the lid.

[0006]

[Action]

 When opening the lid, when the front edge of the push button 5 is pressed, the sliding plate portion 20 integrally retracts, the lid portion 3 is pushed up by the taper portion 22 and the back surface of the reversing hinge mechanism 4 is pushed by the protrusion 25. Then, the lid 3 is opened.

Further, when closing the lid, for example, the lid can be closed only by pushing the rear surface of the lid having a small turning radius forward, so that the lid can be closed with only one hand holding the container.

Further, since the front end of the push button 5 is provided in the recess 9 on the front surface of the cap base 2, the lid does not open even if the container is accidentally tilted.

Further, at the center of the rear surface of the top wall 8, there is provided a threaded cylinder portion 11 for being screwed to the mouth and neck of the container body to be mounted.

The lid 3 has a top wall 13 extending from an upper end edge of a rectangular tubular peripheral wall 12 having a lower end edge abutting on a peripheral edge of an upper surface of the cap base top wall 8, and a central portion of a rear surface of the top wall 13 at a central portion. Has a projecting plug projection 14 that fits into the pouring tube portion 10.

Further, the reversing hinge mechanism 4 connects the upper end of the rear portion of the cap base 2 and the lower end of the rear portion of the lid body 3 with a pair of hinges 15 and 15 provided at a predetermined interval. An inverted L-shaped plate which is formed between 15 and whose upper end is connected to the rear center of the lid top wall 13 via a hinge 16 and whose lower end is connected to the rear center of the cap base peripheral wall 7 via a hinge 17. This is a well-known mechanism that is configured by providing an elastic plate 18 that forms The fitting strength between the pouring tube portion 10 and the plug projection 14 is set to such a degree that the lid is not opened carelessly.

Further, the push button 5 has a sliding plate in which a long hole 19 is formed in the central portion for the escape of the pouring tube portion 10 and the upper surface of the cap base 2 is slidably mounted back and forth. The plate 20 has a portion 20, and a pressing plate 21 is hung from the front edge of the plate 20 to the front end of the recess 9.

A taper portion 22 is formed in the central portion of the front end of the upper surface of the sliding plate portion 20 so as to become lower toward the trailing edge side. The taper portion 22 is formed on the lower surface of the central front portion of the lid peripheral wall 12. It is configured such that it is fitted into a recessed fitting portion 23 having a recessed tapered top portion and the push button 5 is pushed in, so that the inclined surface of the tapered portion 22 pushes up the upper surface of the recessed fitting portion 23. The taper portion 22 is not limited to being provided at the front end of the upper surface of the sliding plate portion 20, but may be retracted rearward from the front end of the upper surface of the sliding plate portion 20 as in the embodiment shown in FIGS. It may be provided in front of the sliding plate. In this case, for example, the protrusion 24 may be vertically provided from the position opposite to the taper portion 22 on the back surface of the base top wall 13.

A protrusion 25 is formed on the trailing edge of the sliding plate portion 20. The protrusion 25 has a shape such that the trailing edge of the sliding plate portion 20 is bent upward, and It is located in the vicinity of the back surface, and is configured so as to come into contact with the back surface of the reversing hinge mechanism 4 when the sliding plate portion 20 retracts.
